Patent GB-686207-A (GB)
Title: Improvements in or relating to high-voltage electric circuit-interrupters
Inventor: LATOUR ANDRE
IPC: H01H33/77
Filed: 1950-11-28
Abstract: 686,207. Gas-blast circuit-interrupters. ETABLISSEMENTS MERLIN & GERIN. Nov. 28, 1950 No. 29065/50. Class 38 (v) The arcing-chamber of an interrupter is formed by the annular space between a fixed insulating tube 13 and a movable insulating tube 7 slidable on the contact rod 1, both tubes preferably being formed from gas-evolving material. To open the contacts, the tube 7 is moved upwards by a crank 8 so as to lift contacts 2 from the rod 1, and the arc formed is forced along the latter into the tube 13 by continued movement of the tube 7, the gases produced exhausting through an outlet 27 and the upper end of tube 13, and cooling devices being fitted if desired. The arc is preferably extinguished as the tube 7 reaches a stop 11, continued movement of the tube moving the contact 1 upwards so as to separate from contacts 4 to produce an isolating break. In a modification Fig. 4 (not shown), part of the arc is shunted by a resistance connected between contacts 2 and an annular auxiliary electrode let into the tube 13 between its ends. In a further modification Fig. 5 (not shown) the auxiliary electrode has outlets opening into a cooling device formed of metal rings, all of which are connected to the resistance. The contact rod may have an insulating extension 23 (Fig. 6) also of gas-evolving material, so that a second arcing-chamber co-axial with the first is formed, thereby simplifying the extinction of small currents. The resistance 19 is connected to a flame arresting device 24. In a further modification, Fig. 7 (not shown), the tube 13 has an annular orifice opening into a chamber where the gases are deionized prior to flowing back into the tube 13 when the pressure therein drops at current zero.

Abstract: 352,827. Flywheels. FÍPPL, O., 10, Bernerstrasse, Brunswick, Germany. Sept. 29, 1930, No. 29099. Convention date, Oct. 12, 1929. [Class 122 (i).] The torsional oscillations of a shaft, such as the crank shaft of an internal combustion engine, are damped by a rotatable mass having a natural periodicity coinciding or approximately coinciding with that of the shaft, the mass being made of a yielding material such as rubber adapted to convert the applied energy into heat by its internal resistance. In the construction shown a solid disc b of rubber is rigidly secured at its centre to the shaft a. Cork, copper, or fibrous material may be used.

Title: Improvements in or relating to valve mechanisms
Inventor: DYKZENL THEODORE J
IPC: G05D23/12
Filed: 1954-10-11
Abstract: 775,783. Thermally - actuated valves. ROBERTSHAW-FULTON CONTROLS CO. Oct. 11, 1954 [Oct. 29, 1953], No. 29278/54. Class 135. A valve mechanism for controlling the fluid fuel supply to a burner, particularly for pilot burner controlled main burners for water heaters, comprises snap-action means 76 including a movable actuating element 84 operatively associated with a valve member 38 for moving it from open to closed position on the seat 36 when the actuating element moves from a first to a second position, thermal means responsive to temperature changes in the medium heated by the burner, e.g. a bulb connected to a capsule 77 having a snap-acting wall 76, for applying a force of predetermined magnitude to the means 76 to move the actuating element to its second position, manually operable means, e.g. the button 54, for moving the valve to its open position, and means for retaining the valve open so long as the actuating element is in its first position. The mechanism is connected in a pipe 98 leading to a pilot burner which when alight heats a bi-metal, a fluid thermal element or a thermal couple to maintain a main burner valve open while the capsule tube 78 leads to a bulb responsive to an abnormally high temperature in'the water being heated. A leaf spring 82, adjustably connected by a nut 86 to the actuating element 84 welded to the capsule wall 76, loads the wall towards valve closing position. The valve is opened by pressing in button 54 so that the ball 56 moves from dwell 64 to dwell 62. When the wall 76 is snapped over towards the left the valve is closed and moves the button outwardly as shown, and the pilot burner and main burners are shut down. In a modification the button, valve, actuating stem and capsule are formed as one unit, and the capsule wall is not self-returning so that no ball detent is provided on the button. U.S.A. Specification 2,603,509 is referred to.

Title: Method of testing wood strips or other materials designed for the production of resonance structures
IPC: G01H7/00
Filed: 1929-09-27
Abstract: 336,766. Kopp, R., and Weickert, E. Sept. 27, 1929. Testing resonant qualities of wood and other material.-Sounding-boards for musical instruments such as pianos, violins, wind instruments, organs, and harmoniums, gramophones, loud speakers, clocks, &c. are built-up ot strips of wood &c. 1 tested acoustically by setting them in a state of vibration by sound waves or electromechanical impulses, as by apparatus 2, 3, diagrammatically shown, and measuring their response by use of a microphone 4 and an amplifying valve 5, in the anode circuit of which is arranged a milliammeter or the like. The strips are tested over the entire frequency range m order to exclude material which fails to give clear tones at all frequencies. Strips, each of which shows a pronounced resonance at its natural period of vibration, are selected. The vibrations may be excited by beats produced by valves operated , at variable frequencies. The variations of anode current may be observed by the use of a milliammeter in circuit or by an electrometer in which mirrors direct the reading upon a steadily moving part, which may be covered by light-sensitive paper. In order to accentuate the response at certain points in the musical scale, for example in the treble of pianos, strips for response at such points are so selected as to show greater resonance than those employed for response at other points, say in the bass.

Filed: 1937-10-28
Abstract: 500,989. Water - sport velocipedes. HARTLEY, F. ST. A. Oct. 28, 1937, No. 29481. [Class 136 (iii)] A water-sport appliance or velocipede consists of a buoyant ring of a size to accommodate within it a performer in an upright position while the ring is standing, on its circumference, and so constructed that it can be maintained in this position and propelled on water by. a climbing or treading effort of the per. former exerted upon the inner circumference of the ring. In one form, the ring is built up of anum. ber (e.g. eight) sections each comprising a pair of segmental hoop members 1 connecting together wood slats 2 which form the running board or tread for the operator. The sections are held together by means of screws 3 and nuts 8, the screws 3 passing through cross-bars 4, which are slotted to receive semi-rigid transverse fins 9 attached to inflatable rubber or rubberized fabric rings or tyres 10, the fins thus serving to attach the rings and also providing a grip upon the water. Alternatively, the rings may be of hemispherical &c. cross-section, and may be attached directly to the slats 2, the ring maintaining its shape wholly by virtue of the air pressure in the rings, the device being completely collapsable. In another form, the inflatable rings are fitted over a rigid metal ring having a series of crossties forming the treads. In a further modification, the device is made entirely of rubberized fabric comprising inflatable rings connected by fins and intercommunicating through transverse pockets which form a tread for the operator. Rope &c. handles or handrails may be provided.
